Batch wrap AAC in mp4/m4a

[Kylezo]

Hey ya'll,

I have a bunch of aac I demuxed from some mp4 videos, and I want to get them over to m4a eventually to throw them into picard and get all my metadata on there and have them compatible with my devices. I have YAMB and Avanti but Avanti doesn't seem to have this functionality built in, and YAMB throws errors every time I try to mux the aac to m4a or mp4 (although really oddly sometimes I get a file output that sounds ok even when it says muxing failed). I was able to batch demux with Avanti very easily and smoothly but I'm stumped for the next step.

It is my understanding that this should be a trivial task with YAMB. Am I an idiot?

Ah, thanks. I'm not too good with command lining, which is why I'm using front end GUIs for everything. I ended up with this:

set thisdir=%1
For /R %thisdir% %%J IN (*.aac) do (
"path_to_ffmpeg\bin\ffmpeg.exe" -v error -i "%%J" -acodec copy -bsf:a aac_adtstoasc -vn "%%J".mp4
)
pause

but I can't figure out how to relocate processed files to a different directory and change the file extension rather than just putting .mp4 after .aac. All my files are *.aac.mp4 now, hah.

set thisdir=%1
set "new_directory=E:\MP4"
For /R %thisdir% %%J IN (*.aac) do (
"path_to_ffmpeg\bin\ffmpeg.exe" -v error -i "%%J" -acodec copy -bsf:a aac_adtstoasc -vn "%new_directory%\%%~nJ.mp4"
)
pause

Thank you sir! The n in %%~nJ is what I was missing.

%%~nJ
